I guess I should have said what the original problem was .. lol
It was stuck in 3rd gear and would only shift up when it felt like it and would not go lower .. He tried to pull start it to see if it would release but these things are made to cut ignition on start up if neutral switch is open.
They suck to work on but most problems can be fixed if you " don't " pull the motor like the manual says.
Stuff it on it's back wheels and tie it there .. start pulling parts.
For the most part you will find that the bolt has come loose on the internal shifter drum but not always ..
here you can see that it knocked the nub off and I was glad to find it. ( the nub that is )
Shifter drum , gasket and a spring that looked like it was about to break all came to about $60.00 at the dealer and it will take about 4-5 hours to do the complete job.

Sounds like you found the issue, but if the clutch basket fingers get grooves worn in them it can make changing gears and finding neutral difficult.
